Very reliable! Never had issues with this truck, its a blessing. Of course like any vehicle with 160, 000 u have minor issues that need tweaking but take care of your truck an she'll take care of you. I also purchased a tent that fits in the truck bed! Just take out the back window and drop the "middle" gate an have access to interior of the truck from the tent, so perfect for cold nights when u need to pump some heat to the tent. This truck isn't just our way to get around its part of the family
A couple of years ago I went shopping for a used truck. I wasn't really in the market for an Avalanche. While I was at a Chevrolet dealer in the Atlanta, GA area test driving a Silverado, the salesperson suggested that I test drive a one owner Avalanche Z66 without the cladding. Out of curiosity I took her for a spin and OMG!!, am I ever glad I did. When I got back to the dealer I bought it immediately. I never really thought I would like an Avalanche until I owned one. I love everything about this truck and the previous owner took excellent care of it. It still looks new. Almost everywhere I go I get compliments on it. Just last night when I arrived at a restaurant someone in the parking lot approached me to try to buy it. This truck has the best ride, drives better, and is more comfortable than anything I've ever owned, including my wife's 2008 Tahoe. In my opinion the interior is MUCH nicer in the 2006 and down Chevy trucks. I hate the interior in the 2007 and up trucks. I will never step up to a newer model truck until they change that UGLY cheap looking hard plastic interior and low grade leather in the newer models no matter how good the exterior is. Anyway, I love the way the Avalanche drives, the power of the 5.3, the ride, convenience, comfort, roomy, locking side tool boxes that double as a cooler, locking tailgate and I mean you name it and I like it. Too bad they stopped building them! If you can find a good used 2006 and down, I would highly recommended it.
It is the best of both worlds. An SUV with the ability to haul stuff that you would not want in the back of your SUV. I 've hauled trees, plants, bags of fertilizer, and rocks.I own a 2003 Z66 with the cladding on the sides. At about the 100,000 mile mark the wheels just fell off. Not literally of course but it seemed that little stuff was going wrong all the time. My water pump went out, then my CD player, then my dash board lights, then the ever popular popping noise in the front end when you turn at slow speeds. Now I have a noise by my glovebox that sounds like someone dropping BB's on a tile floor over an over again. Still waiting on a fix for the popping noise. I still like it.
I love my truck. Ive had all three American made trucks and have never had a truck like this. Its well balanced and gets around better in ice, snow, and mud like no other half ton 4x4 Ive ever been in. The highway ride is unmatched. None of the other trucks seats feel like these. It hasnt given me any troubles. Its got 114 k miles on it and I get 18 mpg on the highway. Show me another 4x4 that does that! All three of my kids fit comfortably and they are all teens. My oldest is almost 5'6" tall.
The ride and seat comfort are above expectations, and the gas millage astounded me.
The trannys are a little week but stepping it up to the 4L80 would fix that.
We have owned this vehilce since new and used it to tow our 35' Travel Trailer extensively; a boat; & a U Haul Trailer. It has been perfect for this and has never given us a moments concern or worry. Without a doubt the most versatile vehicle I have ever owned - carried building materials; Christmas trees; helped my daughter's family move from Florida to Georgia including putting the ride-on mover on the truck bed with no problems. We have now done over 125k miles and I am still on the original brakes. We had one recurring warranty issue with the front steering 'rattling' but this was fixed by Chevrolet on the 2nd review.
Versatility of the vehicle layout. Just like a Tahoe / Suburban inside with availability of 8' x 4' bed with center gate down. Powerful engine easily able to tow boat and trailer with confidence
60/40 mid gate would have been nice - but back seats swabs are 60/40 which has been good enough for us.
